“This has been happening with my two honda cads. I currently have Honda 2023 CRV and 2021 Honda Insight. the Collison Mitigation Braking System brakes really hard for no reason”
NHTSA complaint #11544903, filed 2023-09“The recent NHTSA disclosure of issues with Honda's driver-assistance technologies causes me to write about the troubling performance of adaptive cruise control on my 2021 Insight. When following another vehicle on controlled access highways, the system works fine. However if the vehicle in front enters an exit lane and slows, my car is slowed to the point that the brakes are fully applied, causing vehicles behind me slam on their brakes or swerve to avoid rear-ending me. The ACC does not let go of the car in front of me.”
NHTSA complaint #11470044, filed 2022-06“I have had 6 times where the collision warning has slammed on the brakes when there is no vehicles on the road in front of me. This is very dangerous when vehicles are behind you. I'm afraid that this car is going to cause a reck and get me and my wife hurt. A device that is supposed to help you has the ability to get you hurt. The dealer said that they were unable to get it to do it, and that if I was afraid of it that I could turn it off. Dosen't that defeat the purpose of getting it in the first place. I think Honda is just trying to sweep it under the table. …”
NHTSA complaint #11461413, filed 2022-04“On at least two occasions the automatic emergency braking system has activated with nothing in front of the vehicle. Several instances when cresting a steep rise in the road the forward collision warning system has activated the BRAKE warning light.”
NHTSA complaint #11637606, filed 2025-01“On two (2) occasions, the collision mitigation braking system braked with no reason. It has happened on a quiet and straight line residential street with no other moving vehicle, pedestrian, animal, or any other obstruction in view. After one second or so of braking, it returned to normal. It is available for inspection. I have not spoken to the local Honda dealer about it, and there were no adverser repercussions. There were no prior warnings of any system malfunction.”
